The surface of parasitic protozoa plays an important role in the process of their interaction with cells from the host. The present review analyzes the structural organization of the surface of sporozoa, trypanosomatids, Entamoeba and Trichomonas, as evaluated by conventional transmission electron microscopy, cytochemical techniques and freeze-fracture. In most protozoa, no special region of surface membrane is detected. In others, however, special membrane domains have been described. As examples, we can mention the cytostome found in epimastigote forms of Trypanosoma cruzi, the region of attachment of the flagellum to the protozoon body in Trypanosomatidae and Trichomonadidae, and the inner membrane complex of Apicomplexa.
寄生原生动物的表面在其与宿主细胞相互作用的过程中起着重要作用。本综述分析了通过传统透射电子显微镜、细胞化学技术和冷冻断裂技术评估的孢子虫、锥虫、内阿米巴和毛滴虫表面的结构组织。在大多数原生动物中,未检测到表面膜的特殊区域。然而,在其他一些原生动物中,已描述了特殊的膜结构域。例如,我们可以提及克氏锥虫上鞭毛体形式中发现的胞口、锥虫科和毛滴虫科中鞭毛与原生动物体附着的区域,以及顶复门的内膜复合体。
